The shipment by sea comes as deliveries of aid through means such as truck convoys have faced hurdles. (Humanitarian groups said in a statement last week that their work in Gaza “has been consistently and arbitrarily denied, restricted, and impeded by the Israeli authorities.” Israel says it is doing its utmost to facilitate aid in the enclave.)

Medical care is also sparse. Only 10 hospitals in Gaza are functioning, and they are doing so “minimally,” Tedros Adhanom Ghebreyesus, director general of the World Health Organization, said Saturday.

“Thousands of patients continue to be deprived of health care,” he said, adding that about 9,000 patients “urgently need” to be evacuated from Gaza to receive care for injuries from bombings, cancer and other conditions. More than 3,400 have already been evacuated, he said, “but many more need to be evacuated.” He called on Israel to move faster in approving such evacuations.

Also on Saturday, four members of a United Nations peacekeeping team were injured in a blast while they were on patrol in southern Lebanon, the U.N. Interim Force in Lebanon (UNIFIL) said in a statement, adding that “the targeting of peacekeepers is unacceptable.”

UNIFIL said three military observers from the U.N. Truce Supervision Organization and an interpreter were conducting “a foot patrol along the Blue Line” near the Lebanese town of Rmeish “when an explosion occurred near their location,” adding that all four had been evacuated for medical treatment. The Blue Line is a contentious border demarcation between Lebanon and Israel, which is monitored by the U.N.

It was not immediately clear who or what was behind the blast. UNIFIL said it was “investigating the origin of the explosion.”

Lebanon’s state-run National News Agency said the military observers were from Australia, Chile and Norway, and said they had been “targeted by an Israeli drone.” Hezbollah-affiliated Al-Manar TV, citing its correspondent, also said there was “preliminary information” that an Israeli drone was behind the attack. Neither provided any evidence for the claim, and the Israel Defense Forces denied any involvement, saying in a statement Saturday: “Contrary to the reports, the IDF did not strike a UNIFIL vehicle in the area of Rmeish this morning.”

Earlier this week, UNIFIL said in a post on X that it was “very concerned over the surge of violence occurring across the Blue Line right now. This escalation has caused a high number of civilian deaths and the destruction of homes and livelihoods.”

Since the Oct. 7 Hamas attack, hostilities have soared along the Lebanese border in near-daily exchanges of fire between Israel and Hezbollah that have raised the specter of all-out war.

In November, UNIFIL said one of its patrols was hit by Israeli military gunfire in southern Israel in an attack it described as “deeply troubling.” No peacekeepers were injured but the vehicle was damaged, it said.

Here’s what else to know

A new Biden administration authorization for the transfer of billions of dollars in bombs and fighter jets to Israel has drawn criticism and accusations of hypocrisy, including from some lawmakers. The transfer includes more than 1,800 2,000-pound bombs, the likes of which experts say have been linked to the soaring death toll during Israel’s campaign in the Gaza Strip. Sen. Bernie Sanders (I-Vt.) called the move “obscene,” while Sen. Jeff Merkley (D-Ore.) called the transfer “wrong on every level.” “We have continued to support Israel’s right to defend itself,” a White House official told The Washington Post. “Conditioning aid has not been our policy.”

The United States welcomed the formation of the new Palestinian government announced earlier this week, amid international hopes that the Palestinian Authority could play a role in rebuilding and governing Gaza once the war ends. “A revitalized PA is essential to delivering results for the Palestinian people in both the West Bank and Gaza and establishing the conditions for stability in the broader region,” State Department spokesman Matthew Miller said in a statement Friday. The PA, which runs parts of the Israeli-occupied West Bank, has faced widespread apathy and discontent, as well as international pressure to reform.

An Israeli strike killed 10 Palestinian police officers and wounded several civilians Friday at a sports club east of Gaza City, where police were distributing aid to displaced families, a Gaza civil defense official said. The Israel Defense Forces did not immediately respond to a request for comment on the strike, and The Post could not independently verify the account.

The Palestine Red Crescent Society said 26 members of its team have been killed since the start of the war in Gaza, including 15 workers it says were targeted while wearing the aid group’s emblem, which is protected by international law.

At least 32,705 people have been killed and 75,190 injured in Gaza since the war began, according to the Gaza Health Ministry, which does not distinguish between civilians and combatants. Israel estimates that about 1,200 people were killed in Hamas’s Oct. 7 attack and says 254 soldiers have been killed since the start of its military operation in Gaza.
